Q

ABS extrusion die lip buildup (die drool)

A

ABS die drool=the accumulation of 'residence degradation': cleaning treats the symptoms, temperature-speed matching treats the root; the interval pattern of periodic scoring lines can be used to deduce the buildup shedding cycle, facilitating the formulation of the maintenance rhythm.

Q

Melt fracture on ABS extrusion surface

A

The main line for ABS extrusion surface roughness is 'reducing outlet shear': raise temperature, reduce speed, polish, and add PPA in sequence; when pursuing output, find the balance point between speed and surface quality.

Q

Poor surface gloss of ABS products

A

ABS gloss='mold polishing + melt mold conformance': the mold determines the upper limit, temperature and pressure determine the replication; mold temperature has a great influence on gloss, the mold temperature for high-gloss parts must be given generously, and at the same time don't let degradat...

Q

ABAK poor compatibility delamination

A

The compatibility of ABAK is the decisive factor for alloy performance; 3~8% compatibilizer is the patent-verified optimized range; commercial grades are more reliable than self-blending.; After confirming effectiveness, fix the parameters and practices into the work instructions to prevent recur...

Q

Resonance of laminated parts causes fatigue delamination

A

The essence of the interlayer separation problem is insufficient interfacial bonding force; it needs to be systematically improved from three aspects: impregnation quality, interlayer cleaning, and process parameters.
